Requirements for a Failover Deployment

<

The are several factors that are required to be available to create a failover deployment.

Verify that the following conditions are met.

A hardware-based load balancer. is available.

Only one vRealize Hyperic server in an vRealize Hyperic server cluster should receive agent communications at a time. The load balancer should not direct agent connections to an vRealize Hyperic server instance that serves as the secondary node.

Database Considerations: All nodes in the vRealize Hyperic cluster must share the same database. You cannot use vRealize Hyperic's internal PostgreSQL database in a failover configuration. You must use an external PostgreSQL database.

The database password, and the encryption key used to encrypt the database password on each vRealize Hyperic server instance, must be identical. Supply the same database password and encryption key when installing each of the server instances to be clustered.
